PIAPER-CLIP.

Specification of Letters Patent.

Patented Dec. 10, 1918.

Application filed November 5, 1917. Serial No. 200,392.

7 '0 all whom it may concern:

Be it known that I, HERMAN E. SoHLInBs, a citizen of the United States, residing at Niles, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Paper-Clips; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple and inexpensive paper clip, yet one which will be highly efficient, a prong being provided to penetrate the paper when the clip is turned after application thereof, whereby removal is prevented.

With the foregoing general object in view the invention resides in the novel construction of the clip hereinafter fully described and claimed.

In the drawings,

Figure 1 is a perspective view showing the manner of applying the clip;

Fig. 2 is a similar view after turning the clip so that its prong penetrates the paper;

Fig. 3 is a sectional view on the plane of the line 33 of Fig. 2; and

Fig. l is an edge elevation of the clip.

The device consists of a coil 1 formed of a single piece of wire of any suitable shape in cross section, said coil also being of any preferred formation, such as round, square or triangular. The wire is given one or more turns or convolutions, two being preferably employed.

One end of the wire is sharpened to form 9. prong 2 which is bent toward the adjacent portion of-the coil, this prong being also bent inwardly a trifle in most cases. When the clip is applied to several thicknesses of paper as shown in Fig. 1, turning of said clip in the direction of the arrow will cause the prong 2 to penetrate the paper as shown in Fig. 2, thus preventing accidental removal of the clip, and for the purpose of so turning the clip, the end of the wire remote from the prong 2, is bent across the coil and arched outwardly to a slight'extent therefrom to form a handle 3 adapted to be gripped between the thumb and forefinger as indicated in Fig. 1. Adjacent the handle 3, the wire is bowed inwardly toward the adjacent portion of the coil as indicated at 4 to form a friction brake which prevents accidental turning of the clip after it is once in use as shown in Figs. 2 and 3. The paper is gripped between the brake 4: and the adj acent portion of the coil as indicated most clearly in the last named figure.

From the foregoing, taken in connection with the accompanying drawings, it will be obvious that although my invention is of extremely simple and inexpensivev nature, it will be highly efficient, whether constructed of a single convolution or several. Furthermore, the shape of the coil may be varied and the cross sectional shape of the wire of which this coil is made, is unimportant. For these reasons, I do not wish to be restricted to such details. In fact, numerous minor changes may well be made within the scope of the invention as claimed. For instance, the coil may be either of right or left hand formation.

I claim:

1. A paper clip comprising a coil formed of a single piece of wire and having paper straddling end of sald wire having a prong extending obliquely inward toward the adjacent convolution to penetrate the paper when the clip is rotated, and a handle for so rotating said clip.

2. A paper clip comprising a coil formed of a single piece of wire and having paper straddling and clamping convolutions, one end of said wire having a prong extending obliquely inward toward the adjacent convolution to penetrate the paper when the clip is rotated, the other end of the wire extending across said coil to form a handle for so rotating the clip.

3. A paper clip comprising a coil formed of a single piece of wire and having paper straddling and clamping convolutions, one end of said wire having a prong extending obliquely inward toward the adjacent conand clamping convolutions, one

volution to penetrate the paper when the In testimony whereof I have hereunto set clip is rotated, the other end of the wire exmy hand in the presence of two subscribing 10 tending across said coil to form a handle for witnesses.

so rotating the clip, one convolution of the wire being bowed toward the next convolu- HERMAN SCHLIEBS' tion at the anchored end of said handle, Witnesses:

whereby to form a friction brake to prevent H. E. HEYDENBURG,

retrograde rotation of the clip when in use. ANNA M. ABRAHAM.
